What is ISO 20257-2- Design of floating LNG installations about?

ISO 20257-2 provides specific requirements and guidance for the design and operation of floating LNG storage and regasification units (FSRU).

ISO 20257-2 includes requirements to the jetty when an FSRU is moored to a jetty.

Who is ISO 20257-2- Design of floating LNG installations for?

ISO 20257-2 on the design of floating LNG installations is beneficial for:

Producers of natural gas
Liquid natural gas plant operators
Offshore industries
Inshore FSRUs
Floating LNG
Researchers of design and new technologies for floating LNG
LNG marine transportation

Why should you use ISO 20257-2- Design of floating LNG installations?

A floating storage regasification unit (FSRU) is a vital component required while transiting and transferring liquefied natural gas (LNG) through the oceanic channels. Therefore, FSRU can be termed as a special type of ship used for LNG transfer.

ISO 20257-2 describes the specificities of the FSRU BOG handling and recovery system. ISO 20257-2 fulfils the specific requirements for recondenser. The recondenser has two purposes:

Recondensation of the BOG into the sub-cooled LNG stream from LP pumps
Feeding the LNG HP pumps with liquid and providing liquid hold-up capacity between the LP and HP pumps

ISO 20257-2 states the functions of HD and LD compressors. ISO 20257-2 assists the user with combined vaporizers and ambient air vaporizers.

ISO 20257-2 is applicable to offshore, near-shore, or docked FSRUs and to both new-built and converted FSRUs.

Overall, ISO 20257-2 is helpful as it assists the user with FSRU issues. FSRU warms up LNG for regasification and sends it out as high-pressure according to the user’s demand.
